A double sealing frame with threefold sealing edges offers safe protection and a secure fit for almost all face shapes. The mask body from durable EPDM ensures a great level of wearing comfort even during prolonged use.  ​The comfortable 5-point harness ensures that the mask is easy and quick to don. Additionally, the wide strap design prevents the development of pressure points on the head.  The distortion-free lens with 180° wide angle guarantees a large field of view with excellent periphial vision. There is a choice of impact-proof polycarbonate material (with plastic frame) or scratch-proof and chemical-resistant Triplex glass (an extra stable stainless steel frame).  ​One universal size simplifies logistics and storage. An inside barcode allows for ease of recording and servicing the mask inventory.  The lateral location of the filters does not impede the field of vision of the wearer.  The Dräger X-plore® 5500 is equipped with two lateral bayonet connections for use of the comprehensive Dräger X-plore® bayonet filter series.
